Global infrastructure development, mining expansion, and accelerated equipment replacement cycles have driven long-term growth in the construction machinery industry. Modern machines operate in environments involving heavy shock loads, moisture, dust, corrosive agents, and continuous vibration. As equipment becomes larger, more powerful, and more durable, the mechanical and corrosion-resistance requirements for materials used in structures, hydraulic systems, power systems, and protection components continue to increase.
We supply a complete portfolio of stainless steels, alloy steels, wear-resistant steels, duplex steels, and nickel alloys, supporting plates, sheets, pipes, bars, forgings, flanges, and welding materials. With a global warehouse network, we provide timely deliveries for both prototyping and mass production.
Structural assemblies demand superior strength and weldability
Major structural components such as frames, booms, chassis beams, and support arms must withstand long-term cyclic loading. Materials such as 304, 201, and 430 stainless steels or alloy steels are often used. 304 provides excellent corrosion resistance and weldability for frames and welded beams; 201 offers a cost-efficient solution for medium-load structures; 430 delivers improved heat resistance for protective covers and exhaust housings. In harsh mining environments, duplex stainless steel 2205 is increasingly adopted for its superior yield strength and resistance to chloride corrosion.
Hydraulic systems rely on fatigue-resistant and corrosion-resistant metals
Hydraulic cylinders, high-pressure pipes, and valve components require excellent fatigue strength, corrosion resistance, and dimensional precision. 304, 316L, and 410S stainless-steel tubes are widely used. 316L excels in corrosive or moisture-rich environments, while 304 offers outstanding weldability for manifold connections. For wear-critical hydraulic cylinder components, 410S and heat-treated alloy steels provide superior abrasion resistance.
We offer tube straightening, precision cutting, and polishing services for hydraulic applications.
Powertrain and exhaust systems drive high-temperature material adoption
As emission standards rise and operating temperatures increase, 409L, 304, and 310S stainless steels are widely used in exhaust pipes, mufflers, and high-temperature casings. 409L remains the global standard for construction-machinery exhaust systems; 304 performs better in moisture-corrosion environments, and 310S supports high-temperature zones near the engine manifold.
Lightweight protective components and enclosures
Smart and lightweight construction machinery increasingly uses 304, 316L, and aluminum alloys for operator cabins, external shields, and access panels. We provide fully processed components—laser-cut, bent, welded, and surface-finished—to help manufacturers improve assembly efficiency.
